The role of the multidisciplinary health care team in the management of patients with Marfan syndrome

Consensus Guidelines for Ocular Surveillance of von Hippel-Lindau Disease

PURPOSE

To develop guidelines for ocular surveillance and early intervention for individuals with von Hippel-Lindau (VHL) disease.

DESIGN

Systematic review of the literature.

PARTICIPANTS

Expert panel of retina specialists and ocular oncologists.

METHODS

A consortium of experts on clinical management of all-organ aspects of VHL disease was convened. Working groups with expertise in organ-specific features of VHL disease were tasked with development of evidence-based guidelines for each organ system. The ophthalmology subcommittee formulated questions for consideration and performed a systematic literature review. Evidence was graded for topic quality and relevance and the strength of each recommendation, and guideline recommendations were developed.

RESULTS

The quality of evidence was limited, and no controlled clinical trial data were available. Consensus guidelines included: (1) individuals with known or suspected VHL disease should undergo periodic ocular screening (evidence type, III; evidence strength, C; degree of consensus, 2A); (2) patients at risk of VHL disease, including first-degree relatives of patients with known VHL disease, or any patient with single or multifocal retinal hemangioblastomas (RHs), should undergo genetic testing for pathologic VHL disease gene variants as part of an appropriate medical evaluation (III/C/2A); (3) ocular screening should begin within 12 months after birth and continue throughout life (III/C/2A); (4) ocular screening should occur approximately every 6 to 12 months until 30 years of age and then at least yearly thereafter (III/C-D/2A); (5) ocular screening should be performed before a planned pregnancy and every 6 to 12 months during pregnancy (IV/D/2A); (6) ultra-widefield color fundus photography may be helpful in certain circumstances to monitor RHs, and ultra-widefield fluorescein angiography may be helpful in certain circumstances to detect small RHs (IV/D/2A); (7) patients should be managed, whenever possible, by those with subspecialty training, with experience with VHL disease or RHs, or with both and ideally within the context of a multidisciplinary center capable of providing multiorgan surveillance and access to genetic testing (IV/D/2A); (8) extramacular or extrapapillary RHs should be treated promptly (III/C/2A).

CONCLUSIONS

Based on available evidence from observational studies, broad agreement was reached for a strategy of lifelong surveillance and early treatment for ocular VHL disease. These guidelines were endorsed by the VHL Alliance and the International Society of Ocular Oncology and were approved by the American Academy of Ophthalmology Board of Trustees.

Interprofessional collaboration in the cardiovascular management of Marfan syndrome: A qualitative study based on interviews with professionals

BACKGROUND AND AIM

Patients with Marfan syndrome, who present with a variety of symptoms and complex psychosocial problems, require interprofessional collaboration in their care. However, it is unclear how health care providers contribute to interprofessional collaboration for these patients. The purpose of this study was to determine the characteristics of interprofessional collaboration for patients with Marfan syndrome in the cardiovascular field.

METHODS

Semi-structured interviews were conducted with health care specialists (5 physicians, 2 nurses, and 3 certified genetic counselors) were analyzed qualitatively.

RESULTS

Based on the medical collaboration for the management of cardiovascular complications in patients and their relatives, interprofessional collaboration was identified, such as collaboration and cooperation between physicians and certified genetic counselors, and nursing practice to facilitate interprofessional collaboration. In addition, issues such as difficulties in dealing with and coordinating medical care for noncardiovascular complications, lack of specialist physicians, and lack of opportunities to collaborate with nurses were identified.

CONCLUSIONS

Effective interprofessional collaboration requires the acquisition of Marfan syndrome and genetic knowledge by healthcare providers and the development of a healthcare delivery system based on departments that can provide leadership. In addition, the assignment of nurses to work across organizational boundaries and effective collaboration between genetic counselors and nurses should be considered.

Comprehensive review of aortic aneurysms, dissections, and cardiovascular complications in connective tissue disorders

Connective tissue disorders, including Marfan syndrome (MS) and Ehlers-Danlos syndrome (EDS), are characterized by genetic mutations affecting connective tissue structural integrity. These disorders significantly elevate the risk of aortic dissection, a life-threatening condition. This comprehensive review delves into the intricate interplay between connective tissue disorders and aortic dissection, shedding light on the clinical features, pathophysiology, genetic underpinnings, diagnostic approaches, clinical management, associated comorbidities, and prognosis, mainly focusing on MS and EDS, while also exploring rare connective tissue disorders and forms of cutis laxa contributing to aortic pathology.

Longitudinal follow-up by MR angiography reveals progressive dilatation of the distal aorta after aortic root replacement in Marfan syndrome

OBJECTIVES

To define and compare growth rates of the distal aorta in Marfan patients with and without aortic root replacement using serial MR angiography (MRA).

METHODS

We retrospectively included 136 Marfan patients with a total of 645 MRAs who underwent a median of five MRAs (range: 2-13) at 1.5 T and 3 T in annual intervals. Of these, 41 patients (34.8 ± 12 years) had undergone aortic root replacement. The remaining 95 patients (29.0 ± 17 years) still had a native aorta and served as the control group. Thoracic aortic diameters were independently measured at eleven predefined levels. Estimated growth rates were calculated using a mixed effects model adjusted for sex, age, BMI, and medication.

RESULTS

Marfan patients with aortic root replacement revealed the highest mean estimated growth rate in the proximal descending aorta (0.77 mm/year, CI: 0.31-1.21). Mean growth rates at all levels of the distal thoracic aorta were significantly higher in patients with aortic root replacement (0.28-0.77 mm/year) when compared to patients without aortic root replacement (0.03-0.07 mm/year) (all p < 0.001). Antihypertensive medication, gender, and BMI had no significant impact on the distal aortic growth rates.

CONCLUSION

Distal thoracic aortic diameters increase at a significantly higher rate in Marfan patients with aortic root replacement compared to Marfan patients without aortic root replacement. Further studies are warranted to investigate if the increased growth rate of the distal thoracic aorta after aortic root replacement is caused by altered hemodynamics due to the rigid aortic root graft or due to the general genetic disposition of post-operative Marfan patients.

CLINICAL RELEVANCE STATEMENT

High growth rates of the distal aorta after aortic root replacement underline the need for careful life-long aortic imaging of Marfan patients after aortic root replacement.

KEY POINTS

• Aortic growth rates in Marfan patients with aortic root replacement are highest in the mid-aortic arch, the proximal- and mid-descending aorta. • Growth rates of the distal thoracic aorta are significantly higher in Marfan patients with aortic root replacement compared to Marfan patients without aortic root replacement. • Antihypertensive medication, gender, and BMI have no significant impact on distal aortic growth rates in Marfan patients.

The Unique Experience of a New Multidisciplinary Program for 22q Deletion and Duplication Syndromes in a Community Hospital in Florida: A Reaffirmation That Multidisciplinary Care Is Essential for Best Outcomes in These Patients

In 2018, the first 22q11.2 multidisciplinary program in the state of Florida was created at Joe DiMaggio Children’s Hospital following the new paradigm for best care of 22q11.2 deletion patients. Since inauguration, the clinic flourished despite challenges. Our 22q clinic has 149 patients ranging from ages 0–21. From that total, 138 are 22q11.2DS: 74 females and 64 males (44% Hispanics, 35% Caucasians, 11% African American, 3% Asian and 7% multiracial). Eleven patients are in the 22q11.2 duplication group; 7 females and 4 males (50% Hispanics, 30% Caucasians 10% Asian and 10% multiracial). Our multidisciplinary team has grown to include twelve different specialties to better serve our growing patient population and has adapted to the pandemic by offering virtual clinics. Although there are many 22q multidisciplinary clinics worldwide, our clinic has special characteristics. We have an ethnically diverse group of patients and a large team of mostly bilingual providers who are passionate about and have expertise on 22q Deletion/Duplication Syndromes. Our 22q clinic is based at a community hospital and counts on the partnership of local 22q patient support groups. The program is also unique in that it is now expanding to care for adult 22q patients. Our clinic is another live example of how multidisciplinary care is the best way to achieve the most optimal outcomes in 22q patients, and that if there is a passionate and dedicated team of providers willing to collaborate for these patients, a 22q multidisciplinary program can thrive, succeed and grow at a community hospital.

Oral Health Status in Marfan Syndrome: A Systematic Review and Meta-Analysis of 353 Cases

This meta-analysis aimed to compare Marfan syndrome (MFS) patients with non-MFS populations based on orofacial health status to combine publicly available scientific information while also improving the validity of primary study findings. A comprehensive search was performed in the following databases: PubMed, Google Scholar, Scopus, Medline, and Web of Science, for articles published between 1 January 2000 and 17 February 2022. PRISMA guidelines were followed to carry out this systematic review. We used the PECO system to classify people with MFS based on whether or not they had distinctive oral health characteristics compared to the non-MFS population. The following are some examples of how PECO is used: P denotes someone who has MFS; E stands for a medical or genetic assessment of MFS; C stands for people who do not have MFS; and O stands for the orofacial characteristics of MFS. Using the Newcastle-Ottawa Quality Assessment Scale, independent reviewers assessed the articles' methodological quality and extracted data. Four case-control studies were analyzed for meta-analysis. Due to the wide range of variability, we were only able to include data from at least three previous studies. There was a statistically significant difference in bleeding on probing and pocket depth between MFS and non-MFS subjects. MFS patients are more prone to periodontal tissue inflammation due to the activity of FBN1 and MMPs. Early orthodontic treatment is beneficial for the correction of a narrow upper jaw and a high palate, as well as a skeletal class II with retrognathism of the lower jaw and crowding of teeth.

Magnetic resonance angiography derived predictors of progressive dilatation and surgery of the aortic root in Marfan syndrome

Background

To identify magnetic resonance (MR) angiography derived predictors of progressive dilatation and surgery of the aortic root in Marfan syndrome.

Material and methods

We retrospectively included 111 patients (32.7±16.5 years, range: 7–75 years) with a total of 446 MR angiographies. Aortic diameter growth rates of the entire thoracic aorta and Z-scores were estimated from annual diameter measurements. Aortic root shape was subdivided into three different types: (T0) normal; (T1) localized dilatation; (T2) generalized aortic root dilatation. Aortic diameter, Z-score, age, and aortic root shape at baseline were tested as predictors of aortic root dilatation using a multivariate logistic regression model.

Results

The highest aortic growth rate was observed at the level of the sinuses of Valsalva. Higher aortic root diameters and Z-scores at baseline predicted an increased growth of the aortic root (p = 0.003 and p<0.001). Young age (<30 years) was a predictor for the increase of Z-scores when compared to patients ≥30 years (p = 0.019). 25/111 patients (22.5%) had a T0 aortic root shape, 59/111 patients (53.2%) had a T1 aortic root shape, and 27/111 patients (24.3%) had a T2 aortic root shape. Aortic root shape did not predict further aortic growth (p>0.05). However, significantly more patients undergoing surgery had a generalized aortic dilatation (19/28, 76.9%) than a localized aortic root dilatation (9/28, 32.1%) (p = 0.001).

Conclusion

Larger baseline aortic root diameter and Z-score as well as young age predict solely progressive aortic root dilatation in Marfan patients. MR angiography derived type of aortic root shape does not predict aortic growth, but patients with generalized aortic root dilatation are referred more frequently for aortic surgery.

A specialized multi-disciplinary care program for children with sepsis and multiple organ dysfunction-associated immune dysregulation

The complex physiology and medical requirements of children with sepsis and multiple organ dysfunction syndrome (MODS) challenge traditional care coordination models. While the involvement of multiple clinical subspecialty services is often necessary to support different care processes and individual organ system dysfunctions, it can also delay the diagnostic process, monitoring, and treatment. The logistics of coordinating with many specialty providers for critically ill patients are challenging and time consuming, and often can result in fragmented communication. To address these and other related issues, we developed a new multi-disciplinary consult service focused on streamlining diagnostics, management, and communication for patients with sepsis and MODS-associated immune dysregulation. The service, called the Program in Inflammation, Immunity, and the Microbiome (PrIIMe), is now a hospital-wide clinical consult service at our institution caring for a broad group of patients with immune dysregulation, particularly focusing on patients with sepsis and MODS. In this paper, we summarize the development, structure, and function of the program, as well as the initial impact. This information may be helpful to clinicians and healthcare leaders who are developing multi-disciplinary consult services for children with complex care needs, especially those with sepsis and MODS-associated immune dysregulation. IMPACT: The care of children with sepsis and multiple organ dysfunction-associated immune dysregulation requires rapid and flexible involvement of multiple clinical subspecialists that is difficult to achieve without fragmented care and delayed decision making. In this narrative review we describe the development, structure, and function of a multi-disciplinary consult service at a children's hospital dedicated to helping coordinate management and provide continuity of care for patients with sepsis and multiple organ dysfunction-associated immune dysregulation. This information may be helpful to clinicians and healthcare leaders who are developing multi-disciplinary consult services for children with complex care needs, especially those with sepsis and MODS-associated immune dysregulation.

[Managing transition - Medical follow-up care for adults with congenital heart defects]

Currently, due to medical advances, more than 500 000 patients with congenital heart defects (CHD) are living in Germany, including more than 330 000 adults. In CHD, the aspect of transition from childhood and adolescence to adulthood is becoming increasingly important to ensure long-term success of the provided treatments. This is so important because despite primarily successful treatments, residua and sequels as well as (non-) cardiac comorbidities may influence the chronic course of the disease and lead to increased morbidity and mortality. Adults with congenital heart defects in Germany are insufficiently managed by existing specialized and accredited care structures, despite the great need for follow-up, and their care is largely provided by primary care physicians (general practitioners and internists) and non-specialized cardiologists.Optimized, future-oriented care requires regular follow-up and the possibility of interdisciplinary, integrated medical care of CHD in the long-term course.

Association between subjective well-being and perception of medical care system among patients with Marfan syndrome: A cross-sectional study

Background

This study investigated the association between subjective well‐being and perception for collaboration among clinical departments of adult Marfan syndrome (MFS) patients.

Methods

We performed a self‐administered questionnaire survey to ask about current medical treatment and support systems and subjective well‐being for 114 patients with MFS aged 18–64 years. It was hypothesized that patients’ perception of collaboration between clinical departments would raise their subjective well‐being. Mean value differences were predicted by a multiple regression analysis model, with supportive medical staff, age, sex, aorta dissection, family history, marriage status, and educational background adjusted.

Results

Patients’ perception of collaboration between clinical departments and being married raised SWLS scores (mean difference for patients’ perception of collaboration versus not = 3.41, 95% CI = 0.28, 6.53, p = .03; for married versus single = 5.22, 95% CI = 1.75, 8.69, p = .003).

Conclusion

Our results have suggested that it is necessary to maintain and enhance the medical treatment system with the patients for improving the subjective well‐being of MFS patients. In addition, the result indicated the need for intervention to the patients themselves and also their family so that it allows patients to receive physical and emotional support from people close to them.

Intraindividual comparison of 1.5 T and 3 T non-contrast MR angiography for monitoring of aortic root diameters in Marfan patients

BACKGROUND

Reproducible aortic diameter measurements are crucial for assessment of aortic growth and aneurysm formation in patients with Marfan syndrome. The objective of this study was to perform an intraindividual comparison of aortic measurements at 1.5 T and 3 T using non-contrast magnetic resonance angiography (MRA) in pre-surgical and post-surgical Marfan patients.

METHODS

Forty consecutive Marfan patients were retrospectively evaluated by ECG-gated 2D balanced steady-state free precession (bSSFP) MRA at 1.5 T and 3 T after 363 ± 58 days. 24 patients were before and 16 patients after aortic root surgery. Two readers independently measured aortic diameters at seven aortic levels and rated the image quality/image artifacts (1 = poor/severe, 4 = excellent/none). Contrast-to-noise ratio (CNR) and signal intensity slopes between aortic lumen and vessel walls were semiautomatically determined.

RESULTS

In pre-surgical Marfan patients, interobserver agreement of aortic root diameter measurements was significantly higher at 3 T compared to 1.5 T (p < 0.05). In post-surgical Marfan patients, image quality and artifacts were significantly worse at 3 T compared to 1.5 T (p < 0.05). CNR was higher at 3 T compared to 1.5 T at all aortic levels. Significantly steeper slopes of signal intensity curves were observed at 3 T at all aortic levels (p < 0.001).

CONCLUSIONS

In pre-surgical Marfan patients, non-contrast MRA provides higher reproducibility of aortic diameter measurements at 3 T compared to 1.5 T. In post-surgical Marfan patients, metallic implants result in significantly worse imaging artifacts and reduced image quality at 3 T compared to 1.5 T. Therefore, we propose to monitor the thoracic aorta with non-contrast MRA at 3 T in pre-surgical Marfan patients and at 1.5 T in post-surgical Marfan patients.

Provision of medical health care for adults with congenital heart disease associated with aortic involvement

Background

All patients with congenital heart disease (CHD) are chronically ill from their cardiac disease. Despite the increasing evidence that aortic alterations are becoming relevant, the importance of aortopathy in CHD has long been underestimated. This study was conducted to determine the health status of patients and/or the provision of health services of adults with CHD (ACHD) with manifest aortopathy or at risk thereof.

Methods

In a questionnaire-based cross-sectional survey, the "real life"-care of ACHD was analysed, comparing patients with risk of developing aortopathy and/or manifest aortopathy.

Results

Of the 563 enrolled ACHD (49.6% female, mean age 35.8±12.1, 18-86 years) 56.8% (n=320) had a risk of developing aortopathy and/or manifest aortopathy. Of the 320 patients at risk, 187 (33.2% of the total number) had a proven aortopathy. Within this subgroup, the basic medical care for CHD-independent medical problems was given by primary medical care providers [family doctors/general practitioners (GP) in 89.4% (n=286), internists in 13.4% (n=43), physicians of another specialty in 2.5% (n=8)]. Almost all primary medical care providers knew about the CHD of their patients. Even for CHD-specific health problems, the basic medical care of risk patients was provided by a family doctor or GP in 56.6% (n=181) and by an internist in 18.4% (n=59). 30.0% (n=96) primarily consulted another specialist, including cardiologists. Only 32.8% of ACHD at risk had ever been referred to a CHD specialist by a GP for cardiac problems related to their CHD. In contrast, the need for advice was high for ACHD with aortopathy and related mainly to physical activity, employment and education, pregnancy, rehabilitation or health and life insurance. Only 35.5% of patients at risk indicated that their information on specific care structures for ACHD was sufficient, and a further 38.1% of patients were aware of patient organizations.

Conclusions

Even today, aortic involvement in ACHD is an often-overlooked condition, although considerable negative effects on morbidity and mortality exist. As aortopathy gains in importance with increasing age and complexity of CHD, almost all affected ACHD need lifelong medical advice and access to modern, scientifically based care concepts. According to the study-results, primary care providers and also patients are mostly insufficiently informed about the specialized ACHD facilities. The future goal is therefore to create a better awareness of CHD problems among both primary care physicians and the patients concerned.

Quality of life of children with spinal muscular atrophy and their caregivers from the perspective of caregivers: a Chinese cross-sectional study

BACKGROUND

Spinal muscular atrophy (SMA) is an autosomal-recessive motor neuron disease leading to dysfunction of multiple organs. SMA can impair the quality of life (QoL) of patients and family. We aimed to evaluate the QoL of children with SMA and their caregivers and to identify the factors associated with QoL in a cross-sectional study conducted in China.

METHODS

We recruited 101 children aged 0-17 years with SMA and their caregivers from a children's hospital in China. Twenty-six children had type I SMA, 56 type II and 19 type III. Each child's QoL was measured by the Pediatric Quality of Life Inventory 3.0 Neuromuscular Module (PedsQL NMM), which was completed by the child's caregivers. The caregiver's QoL was measured by the Pediatric Quality of Life Inventory Family Impact Module (PedsQL FIM). Information on sociodemographic characteristics, disease-specific characteristics, and treatments were collected using the proxy-reported questionnaire. Two-sample t tests and one-way ANOVA were used to compare differences in average scores of QoL across subgroups.

RESULTS

Children with type III SMA had a higher average Total score of PedsQL NMM and higher average scores in domains Neuromuscular disease and Family resources than children with type I or type II SMA (p < 0.001). Caregivers of children with type III SMA reported higher average scores in the domains of Physical, Emotional, Social, and Cognitive functioning of the PedsQL FIM than those of children with types I or II SMA (p < 0.05). In addition, disease-related characteristics (e.g. limited mobility, stable course of disease, skeleton deformity, and digestive system dysfunction) and respiratory support were associated with lower average scores of PedsQL NMM and PedsQL FIM (p < 0.05). Exercise training, multidisciplinary team management and use of the medication Nusinersen were each associated with higher average scores in both PedsQL NMM and FIM (p < 0.05).

CONCLUSION

Our study has demonstrated factors that may impair or improve QoL of children patients with SMA and their parents. Particularly, QoL was relatively poor in children with type I and type II SMA as well as in their caregivers compared to those with type III SMA. We strongly recommend that standard of care in a multidisciplinary team be strengthened to improve the QoL of SMA patients. Our study called for increased attention from clinical physicians on measuring QoL in their clinical practices in order to enhance the understanding of impacts of SMA and to make better decisions regarding treatment.

Abdominal Applications of 4D Flow MRI

BACKGROUND

 Four-dimensional flow magnetic resonance imaging (4D flow MRI) provides volumetric and time-resolved visualization and quantification of blood flow. This review presents an overview of possible applications of 4D flow MRI for non-invasive assessment of abdominal hemodynamics.

METHOD

 This review is based on the authors' experience and the current literature. A PubMed database literature research was performed in December 2019 focusing on abdominal applications of 4D flow MRI. We illustrated the review with exemplary figures and movies of clinical cases from our institution.

RESULTS AND CONCLUSION

 4D flow MRI offers the possibility of comprehensive assessment of abdominal blood flows in different vascular territories and organ systems. Results of recent studies indicate that 4D flow MRI improves understanding of altered hemodynamics in patients with abdominal disease and may be useful for monitoring therapeutic response. Future studies with larger cohorts aiming to integrate 4D flow MRI in the clinical routine setting are needed.

KEY POINTS

  · 4D flow MRI enables comprehensive visualization of the complex abdominal vasculature. · 4D flow MRI enables quantification of abdominal blood flow velocities and flow rates. · 4D flow MRI may enable deeper understanding of altered hemodynamics in abdominal disease. · Further validation studies are needed prior to broad distribution of abdominal 4D flow MRI.

Multidisciplinary aortopathy clinics: A systematic scoping review of the literature and evaluation of patient experiences from a newly started clinic in Norway

Background

International guidelines recommend hereditary thoracic aortic diseases (HTADs) to be managed in multidisciplinary aorta clinics.

Aim

To study HTAD patient's experiences with a aortopathy clinic in Norway and to review the literature on aortopathy clinics.

Methods

(a) A systematic scoping review of research on multidisciplinary clinics for HTADs. (b) A cross‐sectional postal questionnaire study to investigate patient experiences with the health‐services. Fifty consecutive patients from the aortopathy clinic and 50 controls in usual care were invited to participate.

Results

The review identified eight publications on aortopathy clinics. Although the papers were not judged for quality, these showed promising results from such clinics in terms of diagnostics and increased adherence to guideline‐directed therapy. The survey constituted thirty‐seven (74%) patients and 22 (44%) controls who responded to postal questionnaires. Both groups reported delays in diagnostics and follow‐up appointments prior to the start of the clinic. Patients indicated high satisfaction with the aortopathy clinic, whereas controls reported poor coordination of medical follow‐up. Individuals in both groups struggled with disease self‐management.

Conclusion

Norwegian patient experiences found the aortopathy clinic beneficial. According to studies included in the review, disease management in aortopathy clinics may improve patient satisfaction, diagnostics and follow‐up. Effect studies may further document the benefits of clinic organization, treatment, cost‐efficiency and patient experiences.

Reliability of non-contrast magnetic resonance angiography-derived aortic diameters in Marfan patients: comparison of inner vs. outer vessel wall measurements

Aortic diameter measurements play a crucial role for the indication of aortic root surgery in Marfan patients. However, for magnetic resonance angiography (MRA)-derived measurements, there is no consensus on whether the aortic wall should be included or excluded in the aortic diameter. The purpose of this retrospective study was to compare the reliability of non-contrast bright blood MRA aortic inner-to-inner and outer-to-outer edge measurements in patients with Marfan syndrome. Forty Marfan patients underwent ECG-gated balanced steady-state free-precession MRA of the aorta at 1.5 T. Two readers independently performed inner and outer measurements at different aortic levels. They rated the image quality of the delineation of both inner and outer vessel wall edges on a four-point scale. MRA-derived diameters of the sinuses of Valsalva were compared with echocardiography-derived diameters. Aortic vessel wall delineation score was rated higher at all levels for inner than for outer vessel walls (p < 0.001). Inter- and intraobserver variances of aortic measurements were smaller for inner-to-inner measurements at the sinuses of Valsalva, sinotubular junction and ascending aorta (p < 0.03). There was a difference of 1.1 ± 2.3 mm for inner MRA measurements (p = 0.014) and 6.9 ± 3.1 mm for outer MRA measurements (p < 0.001) when compared to echocardiographic leading-edge measurements. Inner-to-inner vessel wall diameter measurements in non-contrast bright blood MRA provide more reliable diameters when compared to outer-to-outer vessel wall measurements of the aortic root. Therefore, we propose to rely on inner rather than outer aortic wall measurements in non-contrast-MRA when monitoring aortic diameters in patients with Marfan syndrome.

Full-Mouth Rehabilitation With Implant-Prosthesis in Marfan Syndrome Patient: Clinical Report and Literature Review

The purpose of this case report is to present implant-retained maxillary and mandibular complete overdentures in a patient with Marfan syndrome. The patient initially presented with generalized periodontitis (stage IV, grade C). Due to the progressive nature of periodontal disease, the patient elected to have implant-retained maxillary and mandibular complete dentures. Bilateral maxillary sinus augmentation was performed 6 months before full-mouth extraction, alveoloplasty, and immediate implant placement. Maxillary and mandibular immediate overdentures were delivered. After 4 months of healing, the final overdenture was fabricated. The patient was seen regularly throughout the healing process for peri-implant maintenance. Soft-tissue grafts were completed to increase the thickness of the mucosa around the implants. The patient has been followed for 2 years and is functioning well without major complications. For patients with Marfan syndrome, implant-retained prostheses are a viable treatment option in the presence of a failing dentition.

[Use of the Multidisciplinary Specialised Case Conference at the Freiburg Orbital Centre]

BACKGROUND

The treatment of tumors increasingly takes place in specialised interdisciplinary centres. Therapeutic decisions are usually made at case conferences. Ophthalmologists, oromaximillofacial surgeons, ENT physicians, neurosurgeons, as well as pediatricians, radiotherapists and radiologists are all involved in the treatment of orbital diseases. The aim of this article is to present the concept of a multidisciplinary case conference for orbital diseases and to analyse case numbers, indications, and the influence on the patient's therapy.

METHODS

We analysed an anonymized data set of patients who presented in the case conference of the University Hospital Freiburg from 2008 to 2018 with regard to clinical diagnosis, histological diagnoses, number of surgical interventions, and number of interdisciplinary therapy decisions.

RESULTS

From 2008 to 2018, 545 patients were presented in a weekly conference. Of these, 453 were available for anonymous evaluation. The median age was 56 years (quartiles 41; 69). The most frequent indication was an orbital tumour of unclear malignancy (n = 52; 11%). Further indications included Grave's orbitopathy (n = 39; 9%), orbital pseudotumour (n = 36; 8%), cranial nerve palsy (n = 22; 5%), and orbital lymphoma (n = 22; 5%). The most frequent histological diagnoses were B-cell lymphoma (n = 10; 2%), venous malformation (cavernoma, n = 8; 2%), marginal zone lymphoma (n = 8; 2%), and squamous cell carcinoma (n = 6; 1%). An interdisciplinary therapeutic approach was defined for 174 patients.

CONCLUSION

A high demand for the interdisciplinary case conference was demonstrated. The high rate of primary or secondary interdisciplinary decisions indicates the value of such a conference. Hence, the patient is spared multiple examinations in the individual specialist areas and quick and effective therapy decisions can be achieved.

Postural control abnormalities related to sleep deprivation in patients with Marfan Syndrome

BACKGROUND

Marfan syndrome (MFS) is a rare autosomal dominant connective tissue disorder affecting virtually every organ. Sleep disturbances, associated to high collapsibility in upper airways, are common in MFS; daytime sleepiness could lead to reduction in attention and motor coordination, with detrimental effects on balance.

OBJECTIVE

To evaluate otoneurological function in MFS patients, compared to healthy subjects, and to investigate possible correlations with sleep deprivation extent.

METHODS

Forty-one MFS patients underwent a thorough otoneurological examination, video Head Impulse Test (vHIT), and static posturography. Sleep parameters were recorded by home monitoring. Daytime sleepiness and dizziness-related handicap were screened by means of Dizziness Handicap Inventory (DHI) and Epworth Sleepiness Scale (ESS). Results were compared with 49 healthy controls (HC).

RESULTS

DHI and ESS scores were increased in MFS patients (p < 0,01). vHIT scores showed no between-group effect. Classical (surface and length) and frequency-domain posturographic parameters were significantly increased in MFS with respect to HC (p < 0,01). A positive correlation was found between ESS scores and posturographic parameters in MFS patients.

CONCLUSIONS

An impaired postural control, related to the extent of sleep deprivation, was found in MFS patients. Such results could advocate for screening and treating sleep deprivation and balance dysfunctions in MFS patients.

[Medical care of adults with congenital heart diseases : Present and future]

Congenital heart diseases (CHD) are the most common types of congenital organ defects. Thanks to medical progress in congenital cardiology and heart surgery, most children with CHD reach adulthood. Despite primarily successful treatment residual and subsequent conditions as well as (non)cardiac comorbidities can influence the chronic course of the disease and lead to a higher morbidity and mortality. Adults with congenital heart disease (ACHD) in Germany are not tied to the healthcare structure despite the great need for aftercare. According to the results of the medical care of ACHD (MC-ACHD) study, ACHD centers and specialists in Germany are insufficiently perceived despite increased complication rates and the great need for specialist guidance. General practitioners and patients are not adequately informed about existing ACHD facilities. A better awareness of the ACHD problem should be created at the level of primary medical supply in order to optimize care and to reduce morbidity and mortality. Improved future-oriented patient care includes lifelong regular follow-up and the possibility of interdisciplinary, integrated medical care of CHD.

A Review of Psychosocial Factors of Marfan Syndrome: Adolescents, Adults, Families, and Providers

The purpose of this article was to review the current literature on psychosocial implications of Marfan syndrome (MFS) and its impact on adolescents, adults, their families and to provide important considerations for providers. Since the previous reviews in 2015, numerous studies have been published that are included in the current review. This literature review was conducted using PubMed, Medline, PsychINFO, ERIC, Web of Science, and Academic Search Premier databases and only articles that studied psychosocial factors that influence MFS patients as adolescents, adults, family members, or their interactions with providers were included in this review. Of the 522 articles reviewed, 41 were selected based on the inclusion and exclusion criteria. All articles were peer-reviewed. MFS has various implications that can impact one's life; studies have shown that MFS causes a negative impact on an individual's formative years, quality of life, reproductive decision-making, work participation, and satisfaction with life. Clinicians and multidisciplinary teams should be aware of these factors to provide support focusing on coping strategies for the patient and their family.

The transition of pediatric Marfan patients to adult care: a challenge and its risks

Background

Care for patients with Marfan syndrome (MFS) has improved substantially in recent decades. Increasing clinical knowledge and genetic analysis allow early diagnosis of the disease in childhood. Because of the earlier initiation to preventive and medical treatment, patients' life expectancy has risen. To ensure optimal care, pediatric patients require a safe follow-up regime, multidisciplinary care, and a safe transition to adult care.

Methods

We collected a sample of 149 pediatric Marfan patients, of whom 34 patients had already been transferred to adult care or who were currently transitioning. First, we evaluated clinical aspects of patients that manifest in childhood and are present in the transition process. Second, we analyzed the transition process itself.

Results

We found age-dependent manifestation of organ pathologies. Dilatation of the sinus of Valsalva showed a particularly high prevalence during the transition process and 62% of patients required medical treatment. Mean onset of aortic root dilatation was 9.9±5.8 years. Concerning systemic manifestation in MFS skin striae, wrist and thumb sign, and reduced elbow extension occurred significantly more often in patients who were transitioning than in younger children with MFS. All other clinical Marfan features showed an increased prevalence in patients who were transitioning compared with younger patients. In our cohort, transition was successful in 20 patients (58.9%), 12 patients (35.3%) are still in the transition process and 2 patients (5.9%) were lost to follow up.

Conclusions

Marfan patients in the transition process are already under a chronic disease condition with a high onset of especially cardiovascular pathologies. Although early medical treatment in childhood is effective, the pathologies of the connective tissue require lifelong attention and influence life in many ways. The big challenge during transition is the double change of responsibility from the parents and pediatric doctor to the patient and adult doctor. Consequently, patients in transition process require special attention and close contact with the doctor and the family. A reevaluation by the supervising pediatric Marfan specialist of the successful transition to adult care is indispensable before the pediatric care of Marfan patients is completed.

Improving medical care and prevention in adults with congenital heart disease-reflections on a global problem-part II: infective endocarditis, pulmonary hypertension, pulmonary arterial hypertension and aortopathy

Despite relevant residua and sequels, follow-up care of adults with congenital heart disease (ACHD) is too often not performed by/in specialized and/or certified physicians or centers although major problems in the long-term course may develop. The most relevant encompass heart failure, cardiac arrhythmias, heart valve disorders, pulmonary vascular disease, infective endocarditis (IE), aortopathy and non-cardiac comorbidities. The present publication emphasizes current data on IE, pulmonary and pulmonary arterial hypertension and aortopathy in ACHD and underlines the deep need of an experienced follow-up care by specialized and/or certified physicians or centers, as treatment regimens from acquired heart disease can not be necessarily transmitted to CHD. Moreover, the need of primary and secondary medical prevention becomes increasingly important in order to reduce the burden of disease as well as the socioeconomic burden and costs in this particular patient group.

Impact on Patient Care of a Multidisciplinary Center Specializing in Colorectal and Pelvic Reconstruction

Aim of the study: Many patients with an anorectal malformation (ARM) or pelvic anomaly have associated urologic or gynecologic problems. We hypothesized that our multidisciplinary center, which integrates pediatric colorectal, urologic, gynecologic and GI motility services, could impact a patient's anesthetic exposures and hospital visits.

Methods: We tabulated during 2015 anesthetic/surgical events, endotracheal intubations, and clinic/hospital visits for all patients having a combined procedure.

Main results: Eighty two patients underwent 132 combined procedures (Table 1). The median age at intervention was 3 years [0.2-17], and length of follow up was 25 months [7-31]. The number of procedures in patients who underwent combined surgery was lower as compared to if they had been done independently [1(1-5) vs. 3(2-7) (p < 0.001)]. Intubations were also lower [1[1-3] vs. 2[1-6]; p < 0.001]. Hospital length of stay was significantly lower for the combined procedures vs. the theoretical individual procedures [8 days [3-20] vs. 10 days [4-16]] p < 0.05. Post-operative clinic visits were fewer when combined visits were coordinated as compared to the theoretical individual clinic visits (urology, gynecology, and colorectal) [1[1-4] vs. 2[1-6]; p = < 0.001].

Conclusions: Patients with anorectal and pelvic malformations are likely to have many medical or surgical interventions during their lifetime. A multidisciplinary approach can reduce surgical interventions, anesthetic procedures, endotracheal intubations, and hospital/outpatient visits.

MicroCT imaging reveals differential 3D micro-scale remodelling of the murine aorta in ageing and Marfan syndrome

Aortic wall remodelling is a key feature of both ageing and genetic connective tissue diseases, which are associated with vasculopathies such as Marfan syndrome (MFS). Although the aorta is a 3D structure, little attention has been paid to volumetric assessment, primarily due to the limitations of conventional imaging techniques. Phase-contrast microCT is an emerging imaging technique, which is able to resolve the 3D micro-scale structure of large samples without the need for staining or sectioning.

Methods: Here, we have used synchrotron-based phase-contrast microCT to image aortae of wild type (WT) and MFS Fbn1^C1039G/+ mice aged 3, 6 and 9 months old (n=5). We have also developed a new computational approach to automatically measure key histological parameters.

Results: This analysis revealed that WT mice undergo age-dependent aortic remodelling characterised by increases in ascending aorta diameter, tunica media thickness and cross-sectional area. The MFS aortic wall was subject to comparable remodelling, but the magnitudes of the changes were significantly exacerbated, particularly in 9 month-old MFS mice with ascending aorta wall dilations. Moreover, this morphological remodelling in MFS aorta included internal elastic lamina surface breaks that extended throughout the MFS ascending aorta and were already evident in animals who had not yet developed aneurysms.

Conclusions: Our 3D microCT study of the sub-micron wall structure of whole, intact aorta reveals that histological remodelling of the tunica media in MFS could be viewed as an accelerated ageing process, and that phase-contrast microCT combined with computational image analysis allows the visualisation and quantification of 3D morphological remodelling in large volumes of unstained vascular tissues.

Neonatal Intrathoracic Gastric Volvulus in Marfan's Syndrome

We report a 12-day-old male who was admitted with vomiting because of an unusual early complication of Marfan's syndrome (MS): a sliding hiatal hernia. Initial ultrasound showed no stomach at its normal position and the chest X-ray presented an intrathoracic gas bubble with the nasogastric tube inside. An upper gastrointestinal contrast study confirmed the complete herniation of the stomach into the thorax. Via an exploratory laparotomy it was carefully reintroduced into the abdomen, following a hiatal reconstruction. A Thal fundoplication and a gastrostomy were also performed to guarantee its fixation. Although characterized by cardiac/aortic abnormalities, MS should be considered in any infant with hiatal/paraesophageal hernia, which should be repaired early to avoid gastric ischemia/volvulus.

Importance of Early Detection and Cardiovascular Surgical Intervention in Marfan Syndrome

Marfan syndrome is an autosomal dominant connective tissue disorder that affects multiple systems, including the skeletal, ligamentous, oculofacial, pulmonary, abdominal, neurological, and cardiovascular systems. Cardiovascular complications, which involve the aorta and aortic valve, contribute most significantly to patient morbidity and mortality. A literature review was conducted on pathophysiology of the disease and recommendations for early diagnosis and treatment. Diagnosis largely relies on clinical features and a thorough history. Echocardiogram is used for monitoring aortic abnormalities and disease progression. Aortic valve-sparing surgery is indicated in any valvular abnormality and in patients with a murmur. Aortic root replacement is indicated prophylactically in women who want to give birth with diameters greater than 40 mm, anyone with a diameter greater than 50 mm, and progressive dilatation of greater than 5 mm per year. Medical management involves antihypertensive therapy. It is imperative for all health care providers to understand the clinical features, progression, and management of Marfan syndrome to appropriately care for their patients. Ensuring regular follow-up and adherence to medical and surgical prophylaxis is essential to patient well-being.

Inpatient rehabilitation for adult patients with Marfan syndrome: an observational pilot study

BACKGROUND

Advances in medical, interventional and surgical treatment have increased average life expectancy of patients with congenital heart defects. As a result a new group of adult patients with congenital cardiac defects requires medical rehabilitation. Patients with Marfan syndrome (MFS) are a relevant group among these patients. So far, no reports on the effectiveness of specialized rehabilitation programmes for MFS patients exist. We implemented an inpatient 3-week rehabilitation program for MFS patients at the Muehlenberg-Clinic for rehabilitation and assessed the medical safety as well as the impact of the program on physical fitness and psychological wellbeing of participants by means of an observational pilot study. The comprehensive multidisciplinary program included medical, physiotherapeutic, psychological and social issues. Two groups including 8 and 10 individuals with verified MFS attended the programme. Medically adverse events that occurred during the rehabilitation were registered. Adverse events were defined as: any new cardiac arrhythmias such as atrial fibrillation, ventricular tachycardia, cardiac syncope or any complications located at the aorta. Psychological assessment was performed using Short Form-36 (SF-36), hospital anxiety and depression scale and other psychometric questionnaires. Medical examinations included assessment of maximum power in bicycle ergometry. All assessments were performed at the beginning and at the end of the rehabilitation. Psychometric assessments were repeated 1 year after the end of the programme for both groups, respectively.

RESULTS

Patients were highly satisfied with the programme and improved in almost all psychological and physical fitness assessments. The pre-post-comparison resulted in significant positive changes for mental health (p < .001 for SF-36 Mental Health), fatigue (p < .05 for Fatigue Severity Scale), nociception (p < .05 for SF-36 Pain) and vitality (p < .05 for SF-36 Vitality). Physical fitness improved from admission to discharge (p < .001 for maximum power in bicycle ergometry, p < .05 for maximum nordic walking distance). Considerable improvements persisted through 1 year follow-up. Medical assessments excluded medical problems or adverse events caused by participation in the programme.

CONCLUSIONS

In our study, inpatient rehabilitation was both safe and helpful for MFS patients. They benefited in terms of physical fitness, health related quality of life and in terms of psychological wellbeing. An evaluation of the efficacy of the programme in a controlled design as well as further conceptual improvements of our current program is desirable.

Genetic diagnostics of inherited aortic diseases : Medical strategy analysis

Genetic aortic syndromes (GAS) include Marfan, Loeys-Dietz, vascular Ehlers-Danlos, and Turner syndrome as well as congenital bicuspid aortic valve. The clinical management of these diseases has certain similarities and differences. We employed medical strategy analysis to test the utility of genetic diagnostics in the management of GAS. We chose the standpoint of the cardiologist for our analysis. In the first step, the medical goals in the management of GAS are specified. In the second step, the accuracy of genetic diagnostics for GAS is examined. Finally, conclusions can be drawn about the utility of genetic diagnostics in managing GAS. We found that genetic diagnostics is necessary to exclude GAS, to diagnose GAS, and to specify disease types. Second, combining phenotype with genotype information maximizes the predictability of the course of disease. Third, with genetic diagnostics it is possible to predict the birth of children with causative mutations for GAS and to initiate drug therapy to prevent the onset of aortic dilatation or to slow down its progression to aortic aneurysm. Finally, genetic diagnostics improves prognostic predictions and thereby contributes to a better timing of elective surgery and to a better choice of procedures. The findings of our medical strategy analysis indicate the high utility of genetic diagnostics for managing GAS.
